An accelerator key is a keyboard key (or combination of keys) designated to achieve a specific action. For example, the F6 keyboard key is an accelerator for Zoom to fit of a diagram, whereas Ctrl+A is an accelerator key for Select All. In most cases, the menu option that serves the same purpose as the accelerator lists the corresponding accelerator.

A modifier is a keyboard key applied to a command to slightly modify its behavior or meaning. For example, when using your mouse for resizing a shape in a Rational Rhapsody graphic editor, you can use the Alt key to change the operation behavior from "resize" to "resize without contained."

The accelerator keyboard keys are grouped into three types: application accelerators, accelerators and modifiers within diagrams, and accelerators in the code editor.
